How Many Times Can Self-Sealing Fluid Be Added to Tubeless Tires?
2 Answers
Tubeless tires can be added with self-sealing fluid once. Tubeless tires, also known as low-pressure tires or pneumatic tires, are characterized by: 1. Puncture resistance: The surface of a tubeless tire is made of high-quality rubber, which increases surface tension when inflated, forming a certain pressure on the inner surface, thereby enhancing its self-sealing capability for punctures; 2. Super wear resistance: The rim of a tubeless tire is larger in diameter than that of a regular tire, and it is not affected by the heat from the brake drum during driving. Methods to determine if a tire is tubeless include: 1. Check if there is a TUBELESS mark on the tire, which is an indicator of a tubeless tire; 2. Examine the wheel rim—spoke-type rims are not tubeless tires; 3. Inspect the tire valve—the valve of a tubeless tire is sealed with rubber against the rim.
I've been using tubeless tires for several years, and adding sealant is quite common. Generally speaking, a tire can handle two to three doses without issues, but it depends on the situation: for example, different brands of sealant have varying effectiveness. Last time I added some, I drove about 10,000 kilometers without punctures and didn’t bother with it, but when the liquid dried up a bit, I added a second dose. Be careful not to add it too many times, as the sealant can settle or lose effectiveness over time, and if you get a large puncture, it might leak faster. I recommend checking the tire condition every six months or a year. If you notice more frequent air leaks or significant tire wear, it’s safer to replace the tire. Overall, adding two or three doses is relatively safe, as long as you don’t overdo it.
